Environmental Testing Techniques for Electronics and Materials reviews environmental testing techniques for evaluating the performance of electronic equipment, components, and materials. Environmental test planning, test methods, and instrumentation are described, along with the general environmental conditions under which equipment must operate. This book is comprised of 15 chapters and begins by explaining why environmental testing is necessary and describing the environment in which electronics must operate. The next chapter considers how an environmental test plan is designed; the methods for the environmental testing of components and materials; instrumentation and control of test chambers; shock and vibration test instrumentation; and requirements for specification writing. The reader is then introduced to factors that might affect the reliability of equipment, including high humidity environment; galvanic corrosion problems; high- and low-temperature environments; mechanical and associated hazards; transport hazards; and long-term storage. Problems posed by high altitude and space environments, nuclear radiation, and acoustic noise are also discussed. The final chapter is devoted to environmental protection techniques and looks at the effects of climatic environments on radio interference as well as the effects of the environment on the human operator. This monograph will be of value to materials scientists and electronics engineers as well as those engaged in the design, development, and production of professional and military equipment.

Electronics Reliability–Calculation and Design provides an introduction to the fundamental concepts of reliability. The increasing complexity of electronic equipment has made problems in designing and manufacturing a reliable product more and more difficult. Specific techniques have been developed that enable designers to integrate reliability into their products, and reliability has become a science in its own right. The book begins with a discussion of basic mathematical and statistical concepts, including arithmetic mean, frequency distribution, median and mode, scatter or dispersion of measurements, and the normal and binomial distributions. Separate chapters deal with techniques for calculating equipment and system reliability; safety and derating factors; and the effects of constructional methods on reliability. Subsequent chapters cover environmental effects on reliability; improved reliability through microelectronics or integrated circuits; and failure rates for electronic components. Each chapter concludes with questions to enable students to test their understanding of the topics discussed. This book offers students an introduction to the subject of reliability in a form that is easily assimilated. It also serves as a reference to the various aspects contributing towards increased reliability of both electronic equipment and complete systems.
